Hi all,
Found this accidentally the other day and was wondering if anyone had tried this. When building boost in gear(using a gear higher than you need to load the engine) as you take it out of gear, and before you engage the next gear you quickly tap the accelerator pedal. It must cause the diverter valve to close as you get VERY loud reversion noise
Please don't turn this into a debate as whether reversion is good or bad for your engine/turbo... I'm pretty sure that even though many people believe it to be bad, it's never been proven
